Which of the following is a characteristic feature of mountain soils?

  1. High organic matter content

  2. Deep soil profile

  3. Well-developed horizons

  4. All of the above


Correct Option:
Explanation:

Mountain soils are typically shallow, have low organic matter content, and lack well-developed horizons due to the steep slopes and erosion.

What is the primary factor responsible for the formation of mountain soils?

  1. Altitude

  2. Climate

  3. Vegetation

  4. Parent material


Correct Option: A
Explanation:

Altitude is the primary factor that influences the formation of mountain soils. It affects temperature, precipitation, and vegetation, which in turn shape the soil properties.

How does altitude affect the characteristics of mountain soils?

  1. It increases soil temperature and moisture content.

  2. It decreases soil temperature and moisture content.

  3. It has no significant effect on soil temperature and moisture content.

  4. It varies depending on the specific mountain range.


Correct Option: B
Explanation:

As altitude increases, temperature and precipitation generally decrease, leading to cooler and drier conditions in mountain soils.

Which of the following is a common problem associated with mountain soils?

  1. Erosion

  2. Salinization

  3. Waterlogging

  4. Compaction


Correct Option: A
Explanation:

Erosion is a major problem in mountain soils due to steep slopes, sparse vegetation, and intense rainfall events.

What is the dominant soil texture in mountain soils?

  1. Sandy

  2. Silty

  3. Clayey

  4. Loamy


Correct Option: D
Explanation:

Mountain soils often have a loamy texture, which is a mixture of sand, silt, and clay particles, providing a balance of drainage and water-holding capacity.

How does climate influence the characteristics of mountain soils?

  1. It affects soil temperature and moisture content.

  2. It determines the type of vegetation that grows in the area.

  3. It influences the rate of soil erosion.

  4. All of the above


Correct Option: D
Explanation:

Climate plays a crucial role in shaping mountain soil characteristics by affecting temperature, precipitation, vegetation, and erosion rates.

Which of the following is a common type of vegetation found in mountain regions?

  1. Tropical rainforest

  2. Temperate forest

  3. Alpine tundra

  4. Desert vegetation


Correct Option: B
Explanation:

Temperate forests are common in mountain regions, characterized by trees such as oaks, maples, and pines.

How does vegetation affect the characteristics of mountain soils?

  1. It helps to stabilize the soil and prevent erosion.

  2. It contributes organic matter to the soil, improving its fertility.

  3. It influences the soil moisture content and nutrient cycling.

  4. All of the above


Correct Option: D
Explanation:

Vegetation plays a vital role in shaping mountain soil characteristics by stabilizing the soil, adding organic matter, and influencing moisture content and nutrient cycling.

What is the primary parent material for mountain soils?

  1. Bedrock

  2. Alluvium

  3. Loess

  4. Glacial till


Correct Option: A
Explanation:

Mountain soils are primarily derived from the weathering of bedrock, which is the solid rock that forms the foundation of mountains.

How does parent material influence the characteristics of mountain soils?

  1. It determines the mineral composition of the soil.

  2. It affects the soil texture and structure.

  3. It influences the soil pH and nutrient content.

  4. All of the above


Correct Option: D
Explanation:

Parent material plays a significant role in shaping mountain soil characteristics by determining mineral composition, texture, structure, pH, and nutrient content.

Which of the following is a common soil order found in mountain regions?

  1. Entisols

  2. Inceptisols

  3. Alfisols

  4. Mollisols


Correct Option: A
Explanation:

Entisols are common in mountain regions, characterized by young, undeveloped soils with minimal horizon development.

What are some of the challenges associated with managing mountain soils?

  1. Steep slopes and difficult terrain

  2. Erosion and landslides

  3. Thin and rocky soils

  4. Harsh climatic conditions


Correct Option:
Explanation:

Managing mountain soils poses challenges due to steep slopes, erosion risks, thin and rocky soils, and harsh climatic conditions.

What are some sustainable practices for managing mountain soils?

  1. Contour farming and terracing

  2. Reforestation and afforestation

  3. Proper irrigation and drainage

  4. Minimizing the use of heavy machinery


Correct Option:
Explanation:

Sustainable management of mountain soils involves practices such as contour farming, terracing, reforestation, proper irrigation, and minimizing the use of heavy machinery.

How can mountain soils be improved for agricultural purposes?

  1. Adding organic matter and fertilizers

  2. Improving irrigation and drainage systems

  3. Using appropriate soil conservation techniques

  4. All of the above


Correct Option: D
Explanation:

Improving mountain soils for agriculture involves adding organic matter, fertilizers, improving irrigation and drainage, and implementing soil conservation techniques.

What is the significance of mountain soils in the context of climate change?

  1. Mountain soils store large amounts of carbon

  2. They are sensitive to changes in temperature and precipitation

  3. They play a role in regulating the global water cycle

  4. All of the above


Correct Option: D
Explanation:

Mountain soils are important in the context of climate change due to their carbon storage capacity, sensitivity to climate variations, and role in regulating the water cycle.
